WINDOW.

SPECIFICATION forming part `of Letters Patent No. 57 5,188, datedJanuary 12, 1897. Application filed February 29, 1896. Serial No.581,289. (No model.)

T0 all whom it may concern.-

Beit known that I, MARY VEST, of Birmingham, in the county of J effersonand State of Alabama, have invented certain new and useful Improvementsin Windows, of which the following is a full, clear, and exact description.

The object of this invention is to provide a superior window of thatclass in which the windows may be adjustable vertically and axially on ahorizontal pivot. These ends I attain by weighted chains, a sash, boltsfor connecting the sash with the chains, which bolts are verticallymovable and on which bolts the sash is capable of axial adjustment, andby a fastening device by which the sash may be held incapable of axialmovement. With these means the sash may be freely moved in the frame oreasement of the window and turned on its pivot to open the window.

The invention consists in certain combinations which will be fullydescribed hereinafter and nally embodied in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of a window embodying one form of myinvention.. Fig. 2 is a sectional view of the same,lookin g down uponthe two sashes. Fig. 3 is a similar view taken on the line 3 3 ofFig. 1. Fig. 4

is a detail perspective of the cleat for locking the window-sashes shownin Figs. 1 to 3, and Fig. 5 is a detail perspective of the lockingblockused in connection with the cleat shown in Fig. 4.

The window frame or easement 10 is provided with two vertical slots ateach side, in each of which slots the bolts 16 are vertically movable,said bolts having their outer ends respectively connected with the ringsa, in turn attached to the chains 14, rolling over pulleys 15, carriedbythe easement 10, the chains having weights 11 connected thereto.Pivotally connected to the inner ends of each pair of bolts 16 are thesashes 12 and 13, which are in Figs. 1 to 3 duplicates in construction.Each sash has a locking-cleat 17 at each inner side,and theselocking-cleats are provided with reduced ends 17 "L, slidingin slotsformed in the upper and lower rails of the sashes. The cleats 17 areadapted to move intovvertical grooves 17", formed in the Casement, andby these means 'the window-sashes will be held incapable of movement onthe bolts 1G. It will be seen that the sashes may move vertically whenthe cleats 17 are engaged with the grooves 17.

lVhen the cleats 17 are engaged with the grooves 17h, they are held insuch position by means of blocks 1S, connected to the windowsashes bychains, said blocks heilig inserted in the openings or slots in thewindow-sashes, so as to prevent the return of the cleats. As

yshown in Fig. 4, the cleats 17 are provided with packing-strips l), bywhich an air-tight connection with the sash is eifected.

Pivotally mounted on the window-easement are hooks 19,V adapted toengage in notches (not shown) to be produced in the windowsashes,whereby the sashes maybe held hori- -ing-cleat slidable on the sash andcapable of engaging the leasement to hold the sash from rotation, and ablock iiexibly connected with the sash and capable of engaging thelockingcleatto hold the same in position, substantially as described.

2. In a window,the combination with a window-frame having two verticalslots and two vertical grooves, of bolts respectively Inovable in theslots, a window-sash pivotally connected with the bolts and having slotsat each end of its upper portion, two locking-cleats, the ends of whichare reduced and respectively tted within the slots, the lockingcleatsbeing capable of movement on the sash to extend into the grooves, andblocks flexibly connected with the sash and capable of engaging thelocking-cleats to hold the same in position, substantially as described.

3.
